You should be able to do something like this:

[svn-remote "svn"]
	url = $SVN_REPO_URL
	branches = branches/*:refs/remotes/branches/*
	tags = tags/*:refs/remotes/tags/*
	fetch = cws/c1:refs/remotes/cws/c1
	fetch = cws/c2:refs/remotes/cws/c2
	fetch = cws/c3:refs/remotes/cws/c3
	...

As for generating the individual fetch lines, I would just pipe svn ls $SVN_REPO_URL/cws to awk/sed/perl...
